The pan-genome of Spodoptera frugiperda provides new insights into genome evolution and horizontal gene transfer.

ABSTRACT: Spodoptera frugiperda is a common and severely damaging agricultural pest. In-depth analysis of its population genomics and transcriptomics is crucial for providing references for pest control efforts. This study, focused on the extensive variation in the genome size of S. frugiperda, constructed its pan-genome and identified 1.37 Gb of non-reference sequences, highlighting significant genetic variation within the population. Analysis of Long Terminal Repeat (LTR) Presence/Absence Variation (PAV) suggests that LTR alterations may be one of the driving factors for genome size variation. Additionally, population gene PAV analysis revealed that variable genes are enriched in functions like acetyltransferase activity, which might be associated with detoxification, implying diverse selection pr
